To all wkomz't maycmwern:

Be itknown that I, HENRY PATRICK HoYLn, subject of: the Kin of Great Britain, residing at 16 North Improvements in Apparatus for Washing Coal or the-like and for Separating it from Its Impurities, specification.

This invention relates to improvements in apparatus for washing coal or the like-and separating it from its impurities.

Apparatus according to this invention. comprises a. reciprocating paddle or piston provided with valves and combined with. an

reduced agitation is produced only. during the forward. stroke of thepaddle or piston, whereby material while being progressively agitated or separated-is alsosteadily carried down the mesh plate.

The 'accomp anying' drawings illustrate apparatus made in accordance with th-isinvention.

F igunel is a plampartly in section, Figure 2 a. longitudinal section and- F-igure' a right hand end elevation partly in. section.

Figure 4 is a plan Figure 5 a longitudinal: section on the line w.a,1 Figured, Figure 6' a section-on the line b-b, Figure 5, and Fig ure' 7 an end. elevation of another machine.

Figures 8 and? 9 show modifications ofth paddles.

A tank 1-is divided into two parts 2 and 3, by .a partition at, the impurities being 001- lectedin part 2 and the coal in part, At

the right. hand endiof. part 2 are three pack.

ets 5, separated from. each other by pars titions 6 and from the rest of part 2 by ad- .justable weirs 7. In each of. the pocketsh is a grid 8 pivoted at 9 and held in position,

by a link 10 connected to a weighted lever 11 which is pivotedrat 110. Beneath eachrgrid 8 is a paddle 12 pivoted at and. con: nested to a rod mounted onaneccentric on a shaft 131. In the paddle 12 are valves .121 which close during the upward or forward stroke of. the paddle forcing water through the grids 8. Coal. is supplied. to the grids 8 through. a. chutelt to the top end of the gridswhereit .isheld by adjustahlerplates. 15. In part .3 is an elevator 16 passing; roundv pulleys 161 and, 162. The pnl-ley162 ismounted upon. a shaft 17. upon which a sprocket wheel 1.71 driven by a ailey, Diorham, England, have-invented new and usefulof which the following is achain' from another sprocket wheel on a shaft 18 upon which is a sprocket wheel 181v driven by achain 182. from another sprocket wheel: 132: on the'shaft 131'.

At theilower end of part.- 3: is a valvevlg actuatedthrough a link. r by a handlever 191. When it is desired.- to change the j water,-thevalve 19 is openedi but before so. doing rotation of. the drivingshaft 13,1; and thejpaddles 12 is stoppeolxby meansof a (illltch: 20.

eration coal passes down the. chute lion, to,

purities it is caused tofiow over the 'weirs.

' 7 and passing, down, part, 3..of. the; tank'is raised by, the elevator 16 and; delivered through a. chute2l. The impurities gather on each grid-8 until. their weight overcomes, the weight .on'the lever llof the nawhia. then turnsuponfits pivot 9 allowing it...t.o. descendtogether withthe plate 80 at itsend, so that thei-mpuritie's fall into the part 20f thetank. The impurities are: coll'ectedjby the worm; 21 andmare lifted out; of. the tank bythe hoist 22 and delivered through. adult-e25. Referring to Figures l. to], in,,-ea 'cjh. of three similar pockets 5 is a fixedinclined. mesh plate 8 and a paddle 12' having one end pivoted. at 120 and, theothereild attaohed to.rods:18 actuated eccentrics.130 w on.- a shaft 131., In. the paddle 12 arevalves 10,0

is fed into a. hopper and passes down. .af10.5

chute 14 on, to the mesh plates, .8., At; the

inner end. of the,meshplatesflare pockets 81' in which thedirt; separated" fnom hefi coal; colfle cts. The pocketssl .alteiprovidhdg with doors 22 fhingedat.. and? 1;.9

art 2, is a worm. 21 driven by means; '2 ofva c ain 2110 passing over'asprocket wheel;

1 pots 267. Upon the rods'265 are adjustable weights 268 which prevent the doors 262 from opening until a sufiicient weight of dirt has accumulated in the pockets 81 to overcome the resistance of the weights 268. When the doors 262. are opened the dirt passes down a chute 27 through right and left hand worm conveyors 21 to an elevator 22'by which it is raised and discharged into a chute 25.

In order to prevent the holes in the mesh plates 8 from becoming clogged with dirt, frames 28 carrying scrapers 280 are arranged above them, the frames being connected by links 281 to the ends of levers 282 pivoted at 283, to the other ends of which are pivoted arms 284 forming the straps of eccentrics 285 on a shaft 286. Loose upon the shaft 286 is an arm 287 and fast with it is a ratchet wheel 288 with which a pawl 289 on the arm 287 engages. The arm 287 is actuated by an eccentric 290 on a shaft 29 through a connecting rod 291.

The coal, after being washed, passes from the mesh plates 8 over an adjustable weir 7 and by an elevator 16 to a coal chute 24, the water in the coal being drained from it during its passage up the elevator 16.

The water passing into the pocket 5 is caused, by the action of the paddles 12, to

pass through the mesh plates 8, and the 8 coal upon them, from whence it flows over the weir 7 into a settling tank 30 in which are vertical baflie plates 300'having in them openings 301 arranged out of line with each other, as more particularly shown in Figure 4. In the settling tank 30 are other baffle plates 302 which, together with the bafiie plates 300, intercept the slurry,which settles at the bottom of the tank 30 from which it is removed by a conveyer 303 to an elevator 304 which delivers it through a chute 305 on to the coal elevator 16. Water from the settling tank 30 passes over adj ustable weirs 31 to water pipes 32 connected to the compartment 26 through pipes 33. V Figure 8 shows a modification of the ap paratus, in which a paddle 34 is pivoted at 340 and is oscillated about its pivot. Figure 9 shows another modification of the ap paratus in which a reciprocating piston 35 is substituted for the paddle, In both modifications the action of the apparatus is similar to that above described. 8
